I. Project Overview
(I) Project Overview
The National Aquatics Center is one of the landmark buildings of the 2008 Beijing Olympic Games, and is the only landmark Olympic venue designated by the Beijing Municipal Government to be constructed by the donations of Hong Kong, Macao, Taiwan and overseas compatriots. During the Olympic Games, it undertakes swimming, diving, synchronized swimming and water polo competitions. After the Olympic Games will become a multi-functional large-scale water sports center, can provide the public with water entertainment, sports, leisure, fitness and other services.
The National Aquatics Center is located in the southwest corner of Olympic Park B. The main building is adjacent to the city's central axis, and is arranged in a balanced manner with the National Stadium relative to the central axis.
The east side of the landscape road, the west side of the landscape west, the south side adjacent to the North Top Nyonya Temple, the north side of Chengfu Road. The project covers an area of 62,828 square meters, the race building area of 79,532 square meters, building eaves height of 31 meters, the base area of 177 meters × 177 meters, standard seating 17,000, (of which about 13,000 temporary seats, 4,000 permanent seats). The main structure of the project is designed to have a service life of 100 years. The approved project investment is 1.02 billion RMB. The project started on December 24, 2003 and is scheduled to be completed in October 2007.
(B) Project management system
According to the authorization of the Beijing Municipal Government, the Beijing Municipal State-owned Assets Management Limited Liability Company, as the owner of the project, is solely responsible for the construction and operation and management of the National Aquatics Center. The China Yangtze River Three Gorges Project Development Corporation was hired as the project manager, responsible for the specific construction management.
Designer: China State Construction Corporation National Swimming Center Design Consortium (including China State Construction Engineering Corporation, China State Construction International (Shenzhen) Design Consultant Company Limited, Australia PTW and Arup Engineering Consultants);
Construction Supervision Unit: Beijing Parker International Engineering Consulting Co. Development Company.
Second, the design
At the end of June 2003, our company through the international scope of the design competition, after the technical pre-qualification, expert review, contract pre-negotiation, public voting and technical demonstration, and reported to the municipal government and the Organizing Committee for the Olympic Games, the municipal government on July 28, 2003, the mayor's office meeting approved: China State Construction Engineering Corporation, China State Construction Engineering Corporation, China State Construction Engineering Corporation, PTW Australia Ltd., Australia PTW and ARUP company composed of four design consortium to participate in the "Water Cube" program for the National Aquatics Center implementation plan.
(a) Design concept
This is a building about water. The microscopic molecular structure of water in foam form is amplified into the organic spatial grid structure of the building through the deduction of mathematical theory, thus becoming the building itself. The "Water Cube" is an impeccably pure square that calmly expresses the courtesy and respect for the main stadium, and complements the complete circle of the main stadium.
(ii) structural characteristics
The external wall and roof enclosure structure adopts a new type of steel membrane structure system, which consists of a series of steel mesh frame units similar to cells and crystal bodies and ETFE (polyethylene-tetrafluoroethylene*** polymer) inflatable film **** with the composition.
Third, engineering and technical difficulties
(a) the National Aquatics Center "Water Cube" structural key technologies
"Water Cube" structure follows the most common form of structural composition of nature, the use of a three-dimensional space based on the theory of effective division of bubbles. The structure of "Water Cube" follows the most common structural composition form in nature, and adopts a new type of space structure based on the theory of effective division of three-dimensional space bubbles, which forms the uniqueness of the structure of the National Swimming Center, and it is a challenging work from analysis, design to construction, and it also puts forward a lot of new topics for the development and research of space structure.
(B) Super-large-area ETFE Membrane Structure
The building envelope of the "Water Cube" design program adopts a new type of ETFE inflatable pillow, with a surface coverage area of 100,000 square meters, which is the largest ETFE application project in the world at present.The ETFE facade assembly system has the advantages of material, material, and structure, compared with the traditional building envelope. ETFE fa?ade assembly system compared with the traditional building envelope, has a small material weight, flame retardant, beautiful building appearance, good light transmission and many other advantages.
(C) the key technology of indoor environment system
As the ETFE material inflatable pillow and the traditional building materials in the physical properties are completely different, and the National Aquatics Center on the indoor environment and have very strict requirements, so figure out this special enclosure sound, light, heat characteristics of the indoor environment, and put forward performance improvement measures to ensure that the National Aquatics Center It is very important to ensure that the indoor environmental requirements of the National Aquatics Center are met.
Some of the above problems have been solved, and some are being overcome through relevant tests.
Fourth, the progress of the project construction
December 24, 2003 was successfully held in the National Aquatics Center groundbreaking ceremony, the central government and the Beijing Municipal leaders attended the ceremony, marking the National Aquatics Center officially entered the construction stage.
As of February 2005, the earth excavation, foundation piles and waterproofing of the floor slab have all been completed, including about 400,000 square meters of earth excavation, 4,366 foundation piles, and about 40,000 square meters of waterproofing of the floor slab.
The concrete pouring construction of the base slab started in October 2004, and the concrete construction of the underground part of the structure and the backfilling of the fertilizer tanks are now underway, and some sections have reached plus or minus zero. At present **** completed underground structural concrete 40,000 cubic meters, 8,000 tons of steel reinforcement system, respectively, accounting for 56% and 61% of the total.
V. Engineering Construction Arrangement
